In Reply to:How to obtain the 2mm Cr coatings by spraying posted by Tang
: I am looking for a coating of Chromium about 2mm by plasma or other thermal spraying method. After spraying, the purity of Cr is maintenance (about 99%) Could I get some advice .Thank you!
What is the purpose for the coating and what sort of properties are you looking for?
Most thermal spray methods will produce high levels of oxide content in the coatings except for vacuum plasma spray or possibly cold spray processes. Thickness of 2 mm may also be a challenge.
To my knowledge pure chromium is very rarely used for thermal spray coatings. Experimental plasma spray powders were available many years ago, but I assume by their absence in the main stream of thermal spray coatings today that they found no commercial use. Thermal spray coating replacements for hard chromium electro-plated coatings has always been based on other materials.
Perhaps we should start experimenting with the latest thermal spray technology.
